PRESSURE SENSITIVE ADHESIVE SHEET CAPABLE OF UNDERGOING REPEATED PRESSURE SENSITIVE ADHESION/RELEASE

摘要

An adhesive sheet capable of repeated adhesion and release is provided. A non-adhesive protective material 3 layer is provided to the surface of a substrate 1 coated with an adhesive agent 2 so that the spaces obtained by multiplying the surface area of adhesive sections by the thickness (distance) of the protective material is adjusted so that the adhesive sheet will be capable of repeated adhesion and release.
